To all. QUINN/l, it 'ITML'U concern:

Be it known that l. GERARD ilmitix. 'a citizen of the United States of America, and

a resident of Oakland. county of Alameda, 1 and State of California. have invented a new and useful lmprovenient in lelephone- Meters. of which the following is a specification.

My invention pertains to electroi'i'iagneticall v controlled counting devices and is designed particularly for use in a telephone central oflice.

My invention pertains to the electromagnetic mechanism controlling a counting train and adapted for use with any telephone ineter system in which current of a predetermined strength and direction is passed over a wire at the time registration is desired.

in the preferred form 01" my invention 1 provide for registering when current of a predetermined strength and direction is passed over the wire; in the preferred form o't'nrv invention. the operating coil of the, meter is removed from the wire when the current of the predetermined strength passes. whether the current: be of direction such as to cause the operation of the counting train'ot the meter. or of the opposite direction.

In thc preferred form of my invention. 1

provide a meter having an operating coil adapted to be included in a telephone line, the mechanism controlled by the CUll being adapted to operate in either of two ways.

depending upon the direction of the energizing current, the operation of the mechaisni in one way producing a registration upon the counting train of the meter and removing the controlling coil from the telephone line. and the operation of the n1echanisin in the other way producing no registration upon the counting train of the the ter, but removing the controlling coil from the telephone line.

For the purpose of explaining the operation of the device of my inventioin-lv illustrate a portion of the circuits and apparatus 01"? an automatic telephone exchange with a meter device associated therewith.

I show a system in which the device oi: my invention is associated ,With a sul'iscrihers line and s adapted hy'the circuits and mechanisms of the central oince to register one additional unit upon its counting train l l i l l l the presence of the n upon the tirst answering of called line in response to a call originating upon the subscrihers line pertaining to the meter. 1 show further. ii'ieans whereby lines for terminating calls are divided into two clas. the first case of 'ivl rcontrols the meter or"? the willing line to unit upon a counting train when first answering a call. and the scco 1 class of which controls the meter in iner as not to operate the counting trai L.

changed incidentally to setting up a connec-' tion and .which remains in its changed'condition throughout the continuance of the connection; by the return to normal condition of idleness of this unit of apparatus, the locking circuit is interrupted and the meter mechanism is restored. The. apparatus unit selected would be the first auto-v matic switch involved in the connection,

' and if that switch be individual to the meters line, the meters locking circuitmay take a contact upon any relay armature or other moving part fulfilling the required conditions. I

For controlling the current values upon themeters line, I show a relay in circuit with the called line, having contacts upon its armatures to control the resistance of the circuit of the calling line.

. 5, being found in continuation in Fig. 1 to complete. the talking connection.

Referring to- Fig. 1, the polarized relay and servicemeter shown therein is intended 'tO COIHbln the functionsof a polarizedr'elay ando'f a service meter,- theline winding "lo-being of low resistance and inductance and therefore being adapted to be included directly in a telephone circuit, and'being at the. sametime of sufficient Strength m re: etic. field to move the armature-4',- tofwhic -.the;hloc l; 5 is rigidl the winding'lti, to act as magnet,.the stronger field of magnetization set up by the operate the meter and its .ing units which I show energized, closes line switches of magnet 24 selectsand attached, to lift thespring 20 by a'inovement of the block 5 and thus close the circuit between springs 20 and 19; it will be seen thus that the winding 15 is substantially a relay winding; its efi'ect'being to close the contact between springs QO-and 19, and this it will do regardless of the direction of the energizing current through the windinglo, since the movement-of the armature 4 and block 5 in either direction will lift the spring 20.

Referring to the electromagnetic device, it will be seen that the two cores 14, together with the yoke-piece and-two windings 15 and 16, form an electromagnet of horseshoe form. The association with this electromagnet of the permanent magnet 13 gives it the capability of acting in some cases as it is also evident that after the electromagnet has been caused to act as a polarized electromagnet 1t 1s theirin position, when SubJected to the strongmagnetlzing force of.

winding 16'being capable of over-powering all permanent magnet.

The winding 15 is connected through conductors 21 and 21 with the central oflice circuits of Fig. 3.

Referring now to Fig. 3, 22 is a substation which may institute a call by removing the receiver from the hook and so bridging the telephone set upon the line; 23 is a similar substation which may be called by substation 22; both are of a type of automatic telephone apparatus now in common use, as

olarizin effort of the a non-polarized also is true of the remainder of the'connect and describe in connection with my invention herein. Upon the rising of the switchhook art-substation 22, current from the battery B, or other source of central oflice current, flows through the trip magnet 24, the limbs of the line, the closed telephone circuit at- 22' and [again to the battery B, The trip magnet 24, being respectively as 50, 51, 52, 53. These contacts are thus incommon use in individual tems, and it is their regular office in such systems, as it is in Fig. 3, to extend the limbs of the calling line toward some idle connecting unit. Any of the'usual methods whereby the individual I such as 26,-1 are satisfactory arrangements, for the 'ope ationz of my de-jivice. r .7

The relay 20 is of similar eha *acter to the relay 20, both being in general the two rciays customarily provided in a connector oi at and this places 27. the trip magnet it is energizcthi a cooperating action shall' unism'to close contacts 30. ol.

Xo apparatus 1 i automatic telephone exchange, the regui ter 20 now is operated by the subscriber to tar otlice at such connector being to lind and count:- with it called line in the multiple of lines to which the connector has access. The relays 20 and '29 respectively furnish current for conversation to the substations 22 and 23 These relays as current supp] bridges are counterparts of current supply bridges in manual switchboard connecting cords, and the condensers 30 and 3t similarly interrupt the ctmnecting circuit so that direct current from the relay 20 may not pass to the substation 23 and vice versa.

Further, relay '26 is that which is known in ordinary automatic practice the bridging relay relay 20 is that which is known as the back bridging relay of the connector. The relay 2t) may be of whatever resistance the ordinary features of the telephone systems reuire: the relay 20, however, has two pairs ot wnnhng's, one high and the other low in resistance, a suggested resistance being 250 front ol? the connector, and the L is clcsed I FA .32}, which contacts remain closed until relcasec byahe release magnet if. so also it holds contact 2? closed as is usual in contacts asstmiated with such tripping ol individual autciuatio switches.

The attraction of the armature cl 101, energizes release relay lOl. which is so constructed that it re ponds only to current changes in its hell}; when the changed condition is maintained for a pie determined peril d. -The impulse transmitinterrupt the line a predetermined, num er of times, the number of which is determined by the directory number of the desired line. each of these interruptions being very brief and the closure therebetwcen being also very brief. The durations of the interruptions and closures respectively, are such that relay 103 responds and relay 10% does not respcnd. mitted to release its armature for each circuit interruption, opening the front contact but not afiecting relay l0-l and closing its back contact which closes in successive closures, the circuit extending from earth through back contact 103, front contact 1.0-1, helix of 105. vertical magnet 100. side switch arm 10? and battery to earth. ltelay 105 is so constructed mechanically that it attract. its armature upon rholirst ot these impulses but does not release it between. successive im ohms each 'lor windings 20 and 2,000 ohms 1 each for windings 20. such resistances in the relay 20, ance of winding; may be 50 ohms.

subscriber at suhstationx'li closes his line at the switchhook and by dial interrupts thetline in series of impulses at 33). The closing of the line operates the trip magnet ll, grounds the conductor at 27, and closes all the contacts 30, 51,

A description. of the line switching de vice whose parts are shown at 24-, 4-2, 50, 51, 52 and will be found in the ll'csfm-n Electrician of January 11th. lt tl and 25th. 1908. Relay 40 now is energized by current from battery B through 40 to ground at 52. Trip magnet 24 thus is cut oli' from the line,

means of the usual l s l l l l l l l pulsesj however. it releases its armature alter the cessation of the last impulse. Vertical magnet 100 has responded to each impulse and has ett'ected the moving of selecting switch brushes or wipers 108, 108', 106', as required in systems of the general type described in the 'iublication above re'ferred to. By the attraction ol armature ot relay 105 circuit was closed from earth through that armature, throughhelix in the private magnet 1,09 and through battery to earth, energizing private magnet 10$). during the series of impulses and deenergizingr itafter the seri s and after the release of relay 105. The dee iergization of private magnet 109 moves all side switch levers to the middle position. In this position relay 103 is held energized overthe line circuit, holding relay 1.0% energized also. A circuit is established from battery through switch arm 107, .rotary magnet 110 and interrupter 11.1, be-

This energization of private magnet 109 continues so long as busy trunks are passed over by the wiper 108" but as soon as an idle trunk is found, relay 104 of thgse'lector of that trunk being released, the circuit-of 109 is discontinued, and by the release of magnet 109 the side switch arms of the first selector F are advanced to the third position, that being the position shown in the drawing. By .the advancement of the side switch arms to the third position, relay 103 of the second connector S is energized and relay 104 also, continuing the energization of release magnet 104 of the first selector F through the circuit from battery, helix of. 10% of F, switch arm 112, brush 08","ar1nature of relay 101 of second selector S, switch arm 113 to its first contact, and through supervisory relay 118 to earth. The two relays 104 of F and 104: of S are in multiple in this circuit. The second selector S is controlled in identically the same manner by a second series of breaks at'the controlling device 39, and connection is established thus from substation 22 to connector C of Fig. 6. The

the connector and bymechanism which is disclosed. in the publicationabove referred! to, the connector responds to such impulses by moving its line iipers to find the called line. 7

When the called line has been rung upon inv the usual Way and the subscriber responds at substation 23, the relay 29 is energized. The closing of contacts 33 and 33 places the windings 26' iii-shunt with the windings 26 in' relay 26, and as a conse quence of this shunting an increased volume of current flows tothe substation 22 through the relay winding 15. This permits to fioW through 15 the. strongest current which can flow through that winding but to strengthen any current is not sulficient to overcome the vice, and is sutficient only, to attract one or the other of the ends of the armature 1, operating at the sametime to repel the remaining end; for'the attractionot both movement of through windarmatureit and closes contact 20-19 by atof armature 4,, the direction of the current, from plus pole of 21', 15, 21, in the order mentioned, being proper vto'causeiithe attraction of that end of armature 4. This movement of the armature 'does'two things Spring 20 makes contact with spring 19 and r arm 2 oi counter 1 is advanced from position 0 to positlona because of the rocking of armature 4 upon its pivot 7. Armature 4 is pivoted at 7 on carriage 6, which carriage is pivoted at 8 upon frame 9. The carriage 6 normally is held in position against adjustable stop 10 on frame 9 by tension of spring 12 which is attached adjustably to post 11. The ampere turns of Winding 15 are insufhcient to move carriage 6 against the tension of the spring 12, but the closing of the circuit through winding 16 (the circuit is B, 25, 16, 20, 19, 28, 27, earth) increases the magnetic flux to such an extent as to cause both cores to attract the armature 4, and to cause carriage 6 toswing on the pivot 8. The movement of the carriage 6 thus permits armature 4: to advance until it is in contact with both cores of the magnet; the counter arm 2 thus is advanced through link 3 from position a to position Z). The mechanism of the counter 1 is such as to register one additional unit on its countin-g train by the movement of arm 2-f ron1 position a to position Z2 and a registration thus is made upon the connection h re considered. Further, as carriage 6 permits armature 4 to advance, I the inclined surface of spring 20 and lifts. springs 20 and 18, causing spring 18 to rise and make contact with spring 17, thus shortcircuiting line winding 15; spring 20 maintains contact with spring 19 and the relay thus remainslocked and the line winding remains short circuited throughout the ensuing conversation.

The conversation having been finished, the hanging up of the receiver at substation 22 opens the. line circuit, releasing relay 26 of the connector. In the usual way, through contact not shown in Fig. 3, the connector releases and returns to its normal position. In so doing a ground is placed on conductor 41, "energizing release magnet 42. This magnet is the usual one of individual line switches in standard automatic systems audits oflice 'is to restore the individual line switch to normal condition, opening contacts 50, 51, 52, 53 and contact 27. As 27 opens, the magnets 0t Fig. 1 are no longer energized by either of their Windings and so the armature -"isrelea'sed and the block 5 acts upon returns to its normaltondition and position.
